[QUOTE="Nifft, post: 5357321, member: 6562"] "Much" = enough to give significant tides, promote vulcanism, and keep the planetary dynamo working longer than it otherwise would have worked. It isn't a [B]good[/B] fiber optics cable, but a nice thick atmosphere can carry light around the curve of a sphere, and ours does. Their atmosphere could easily be thicker, what with their planet having a higher surface gravity. Forget UV and just think about violet & blue light. There could be crops which will grow in a twilight zone which never sees their sun. Yep, but that energy [b]is not heat[/b]. It's chemical. The paragraph after the one you quoted hints at this same point: ... but sure, I could have spelled that out more explicitly for you; and yes, deep sea vents on both sides of the planet would have plenty of non-photosynthetic life. But: so what? How are those vents relevant to life [b]on the surface[/b] of the night side? Here's one from a link on page 3: I've bolded the relevant passage. It's in a post by [b]Camber[/b].
